Abstract : The discovery, study, and eventual remediation of pollution that threatens water resources are very important in maintaining the health of the environment and people. However, the discovery of many types of pollution is often difficult. This project focuses on a method used to discover hidden contamination--soil gas surveying. The Rose-Hulman Institute of Technology campus in Terre Haute, Indiana is on the site of an old farm. The campus has an old gasoline station on its border, a chemical storage building on the grounds, and areas where fuel, oil, and solvents are used and stored by the physical plant operation. There was a possibility that underground contamination might be present from these operations. Contaminants typical of these types of operations include Benzene, Toluene, Ethylbenzene, and m, p, and o Xylenes. Using the first letter of these contaminants produces the acronym BTEX. BTEX, chemicals used in the processing of petroleum products and other manufacturing. Other contaminants common in these types of operations include chlorinated solvents such as Trichloroethylene and Tetrachloroethylene. These are important not only because of the high possibility of their existence but also their high toxicity. No significant areas of contamination were found for the contaminants tested. A detailed description of the method and results of testing are presented. Recommendations for improved management of potential contamination areas are also presented.
